Reactivity of Alkenes Alkenes are hydrocarbons containing a carbon-carbon double bond The atoms around the carbon-carbon double bond adopt a planar arrangement and the bond angle is 120o The bondin...
Halogenation of Alkanes Free-radical substitution of alkanes Alkanes can undergo free-radical substitution in which a hydrogen atom gets substituted by a halogen (chlorine/bromine) Since alkanes a...
Unreactive Alkanes Strength of C-H bonds Alkanes consist of carbon and hydrogen atoms which are bonded together by single bonds Unless a lot of heat is supplied, it is difficult to break these stro...
Benzene Kekulé structure for benzene Kekulé suggested that benzene was a hexagon with three double bonds It was therefore equivalent to three ethene molecules Problems with Kekulé’s structure for b...
Primary, Secondary & Tertiary Atoms Alcohols and halogenoalkanes Primary alcohols and halogenoalkanes are those in which the carbon atom bonded to the functional group is attached to one other...
3-D Modelling Representing 3-D molecules on a 2D surface is not easy and the best way to understand 3-D structures is to use modelling kits or 3-D modelling software, such as ACD Labs ChemSketch Fo...
